HAT-TRIMIVHNG MACHINE.

SPECIFICATION forming part of Letters Patent No. 387,692, dated August 14, 1888.

Application filed March 10, 1888. Serial No. 267,713.

To a. whom it nuty concern:

Be it known that I, SAMUEL T. NEWMAN, of Danbury, in the county of Fairfield and State of Connecticut, have invented a certain new and useful Improvement in Hat-Trimming Machines, of which the following is a specification.

My improvement relates to the class of hatmachines employed for trimming the brims of hats.

I will describe a machine embodying my improvement in detail, and then point out the novel features in claims.

In-the accompanying drawings, Figure 1 is a side elevation, partly in section, of a hat-machine embodying my improvement. Fig. 2 is an end view of the same, also partly in section, and looking in the direction of the arrow, Fig. 1. Fig. 3 is also an end view looking in the same direction. Fig. 4 is a detail view of a certain pattern-cam employed in the machine. Fig. 5 shows a slight modification of certain parts.

Similar letters of reference designate like parts in all the figures.

Adesiguates the frame ofthe machine. Extending from the frame is an upright, a, from which upright extends horizontally an arm, a. The arm a has an upwardly-extending portion, a in which is formed a slideway. Adapted to bc slid up and down within the slideway is a slide, B. This slide is manipulated by means of a lever, B, fulcrumed upon the portion a of the frame. The lever B is loosely connected to the slide B by means of a pin, 6, extending from the slide into a slot, 1), formed in the lever. Secured to the slide B is a rod, B This rod is provided atits lower end with a circumferential flange, I). Mounted loosely upon the rod B is a spider, B. Below the spider B is another spider, B. This latter spider is also loose upon the rod. Between the spiders B B is arranged an expansible and contractible cushion, This cushion is preferably made of india-rubber and is hollow. It is to be filled with air and hermetically sealed.

0 designates a frame, shown as comprising four upright arms, 0. These arms are rabbetednear their upper ends and upon their inner sides. A ring, 0, provided with a cirthat the hat-body is inverted.

(No model.)

cumferential flange, c, is supported by the arms 0 at their upper ends, the flange 0' ex tending into the rabbets formed in said arms. The ring C constitutes in effect part of the frame 0. It is of the shape and size circumferentially of the hat-body to be manipulated. I have shown a hat-body, C arranged within and supported upon the ring. It will be seen The ends of the arms of the spider B are bent in such manner that when moved downwardly by means of the lever B they will extend over the brim of the hat and its support and will operate to secure the brim. Further downward movement of the spider B is therefore prevented. The continued movement of the rod B causes the cushion to be compressed between the spiders B B. Its sides are thereby distended and come into contact with the hat-body, securing it firmly in position on the ring C. When the lever B is moved in the other direction, the parts supported by the slideB are moved away from the hat-body, and the latter may then be easily removed from the frame. The parts supported by the rod B constitute a securing device. The use of an eXpansible and contractible cushion is advantageous, be-

cause, while it firmly secures the hat-body in position when compressed, it will not mark or deface the hat body. At the same time it will readily accommodate itself to bats of different sizes.

Extending downwardly from the frame C is a shank or stem, D. This shank extends loosely through a suitable aperture in the frame A. Below the frame A the shank bears a wheel, D. This wheel is provided with a circumferential groove constituting a pulley, cl, and with a circumferentiallyex-tending se ries of gear-teeth, d". Engaging the gear-teeth cl is a gear wheel, D This gear wheel is loosely mounted upon a stud, d extending from the frame A. Secured upon the upper side of the gear-wheel D is a bevel gear-wheel, D This gear-wheel meshes with a bevel gearwhecl, D, loosely mounted upon a shaft, D secured at one end in the frame A and at the other end in a standard, D. Upon the shaft D are loosely mounted a driving-pulley, D and a loose pulley, D The driving-pulley is provided with a hub, (1*. A pin, d extends from the hub d. This pin extends loosely into a socket in the hub and is secured in position by a set-screw, (1. Its extent beyond the hub may therefore be varied. hen the driving-pulley is rotated, the pin (1 will,when it is desired to drive the machine, comein con tact with a pin, (1, extending beyond the side of the gear-whcel D. The frame 0, bearing the hat body,will then be rotated. The pins (2 d constitute in effect a clutch.

I desire to automatically stop the machine each time the frame has made one complete rotation. To accomplish this I cause the withdrawal of the pin (1 out of the path of the pin (1 The rotation of the gear-wheel I) will therefore atonce cease. The pin (1 is rigidly mounted at one end in a sliding piece, d ,(here shown as in the form ofa wheel. It is loosely mounted on the shaft D The pi n d extends loosely through an aperture in the gear-wheel D. This lastnamed gear-wheel is provided with an enlarged hub, c. This hub has an internal recess, 0'. Upon the sliding piece (2 is asleeve, c", which extends into the recess a. A coilspring, 0, surrounds this sleeve. The tendency of this spring is to force the sliding piece (1 away from the gear-wheel D and toward the frame A. The sliding piece 11 is provided with a pin or projection, 0. Normally this pin or projection will extend into a recess, o in the frame A. The sliding piece (I will then be retracted far enough to withdraw the pin (1 from the path of the pin (1. When it is desired to start the machine, the sliding piece (Z is moved outwardly against the resistance of the spring c until the pin or projection c" is clear of the recess 0". The parts will then occupy the posit-ion shownin Fig. 1. The gearwheel D and the sliding piece 11 will thus be enabled to make a single complete rotation. \Vhen the pin c again comes opposite the recess 0 it will be sprung into such recess and the machine will thus be at once stopped. I have shown two means for manipulating the sliding piece d to cause the withdrawal of the pin from the recess. In one of these I employ a lever, E, constituting a shipper, fu1 crumed upon a pin or stud, f, extending from a projection on the main frame of the machine. The lower portion of this lever is bifurcated and the bifurcated portions extend down \vardl y about the sliding piece d. The sliding piece (P is provided with a peripherical groove, into which extend pins or proj cctions upon the bifurcated portions of the lever E. When the upper or free portion of the lever is moved in one directiomthe sliding piece is moved out wardly against the resistance of the sprin By the other means which may be employed, and which is shown in dotted outline,the lever E, instead of being fnlcrumcd upon the pin or studf, is fulcrumed near its upper end upon a pin or stud, f. Upon the lever B is a toe or projection, f, which,when the lever is moved in a direction to effect the securing of thehatbody, as described, will come in contact with the lever E, moving the latter outwardly, and

thereby causing the operation of the sliding piece.

I will now describe the means for trimming the brim of the hat, in which G G designate rotary knives, between which the brim of the hat will pass as the latter is rotated in manner described. These knives trim offthe brim to the desired width. The knives are mounted upon short shafts g y, mounted in suitable hearings in a sliding piece, G. Rotary motion is transmitted to the shafts 1g, and consequently to the knives, by gear-wheels g 1 which mesh and are mounted upon said shafts, respectively. Motion is transmitted to the gear-wheels by means of a belt, y, passing about the pulley (I, pulleys y", mounted on the main frame, pulleys g on the sliding piece G", and over a pulley, g, on the shaftg. The portion of the sliding piece G in which ismountcd the shaft 9 has a hinged connection with the main portion of the sliding piece. It may therefore be rocked backwardly, so as to raise the knife G to admit of the insertion of the hat-brim. I have shown the gear-wheels g 5 as provided with curved gear-teeth to admit of rocking one gear-wheel upon the other withoutimpairingtheengagementof the teeth.

The sliding piece Cl is mounted in a sliding piece, G, and is adapted to be slid to and fro in a slideway, 9", formed in the sliding piece G". The sliding picceG is similarly mounted on a sliding piece, G, which latter is adapted to he slid to and fro in a slideway formed in the frame A. The sliding piece G isprovidcd with a downwardlyprojecting portiomg". Upon this downward] yp rojccti ug portion, and near the lower end thercof,is mounted a roller or bowl, 9. This roller or bowl extends into an elliptical groove,j, formed in the face ofan expanding and contracting pattern-cam, J J. I designate this a pattern -cam because during its rotation it causes the movement of the knives G G nearer to or farther from the hat-body, thus causing the knives to cut more or less material from the brim at different parts of the brim, as desired. The patterncam is composed of two portions, J J, each of which forms, approximately, one half of an ellipse. These two portions are supported by the wheel I). This support is effected as follows: Upon the under side of the wheel D is a V-way groove extending diametrically across the wheel. Into this groove extends a V- shaped projection on the parts J J of the pattern-cam. The parts J J may beslid to and fro in the V-way toward and from each other. The parts J J are united by springs j jflextending between them, the tendency of which springs is to draw said parts toward each other. Of course as the pattern-cam is supported by the wheel 1) when the latter is rotated rotary n10- tion is imparted to the cam. As the roller or bowl 9" on the portion 9'" of the sliding piece G extends into the elliptical groove j,the cam as it rotates will cause the roller or bowl to be moved nearer to or farther from the center of rotation of the cam and the sliding piece G to be slid to and fro. As the sliding piece G carries with it in its reciprocations the sliding pieces G G, and consequently the knives G G, the latter are caused to trim a greater or less width of material from the brim of the hat.

I not only desire to cause the knives to cut a greater or less width of material from the brim, but I also desire to be able to vary the points in the circumference of the brim where the variations of depth of cut shall occur. Some shapes of hats require the brim to be wider in front and narrower at the sides than others, and it is to effect these desired variations that I employ the mechanism about to be described.

J designates a pattern device. This device comprises, essentially, a hub, Z, and a number of projections or spokes, Z. The hubis mounted upon a stud extending from an upright or standard, Z, which latter is secured to the floor or other support beneath the machine. The projections or spokes Z vary in thickness, but are of uniform width. The variations in thickness are more clearly shown in Fig. 1. The uniformity of width is more clearly shown in Fig. 2. All of the projections or spokes are elliptical in the cross-section. This pattern device co-operates with the pattern-cam J J. The adjacent edges of the two portions J J of the latter are provided with notches 1*, which notches are rectangular in outline. If the two parts J J were brought into contact, these notches would form a substantially square opening through and at about the center of the cam. Each of the projections or spokes Z on the pattern device is adapted,as occasion may require, to be inserted near its free end into such notches, and the springs j j will force the portions J J into intimate and constant contact with the projection or spoke. As the pattern-cam rotates, its parts J J will be permitted to come more or less close together,according to the thickness of the projection or spoke within the notches, whereby the degree of reciprocation of the sliding piece GR, and consequently the movement of theknivesGG', toward or from the hat-body is increased or decreased at the time and places desired.

It will be seen that when desired the sliding pieces G2 G3 G may be locked together by clamping-pieces P 1?. They then move as one piece. By loosening the clamping-piece P the sliding piece G may be moved nearer to or farther from the hat-body, so as to cause the initial cut of the knivesto be made at the desired distance from the hat-body. A gage, 0, on one of the sliding pieces and a pointer, 0, on the other will indicate the proper position of the knives. By loosening the clamping-piece P the sliding piece G may be moved into such a position that an upwardly-projecting portion, 10, thereon may be brought into contact with a projection, at, extending from the side of the ring 0. This adjustment takes place when the machine is being set for operation. As the rings 0 vary in diameter according to the sized hat to be operated upon,

is effected by adjusting the sliding piece G as described.

Of course it is to be understood that, the parts having been properly adjusted to a given size and kind of hat, the brims of all the hats subjected to the trimming will receive the same out until the parts receive different adjustment.

Instead of using rotaryknives to cut the brim of the hat, 1 may use a single stationary knife, as shown in Fig. 5. In this case, also, the swinging section of the sliding piece G2 bears the knife. Beneath the knife and extending from the sliding piece G is a cutterbed, 8. The hatbrim as the hat is rotated passes beneath the knife severing the desired portion from the brim.
